The new AeroWeb Low-VOC Aerosol Contact Adhesive/Primer from Mule-Hide Products Co. was designed to boost productivity. According to the manufacturer, the product delivers aggressive adhesion and a quick drying time while going on as much as 60 percent faster than traditional roller-applied adhesives.

The new adhesive can be used in a wide variety of applications, including adhering standard TPO and standard EPDM membranes to horizontal and vertical surfaces; adhering fleece back membranes to vertical surfaces; enhancing the bond between Mule-Hide F5 Air & Vapor Barrier and various substrates; and priming unexposed asphalt prior to applying Mule-Hide HeliX Low-Rise Adhesive for insulation attachment.

AeroWeb’s low-VOC (volatile organic compound), methylene chloride-free formula provides powerful adhesion and a quick drying time in a wide range of temperatures, helping contractors avoid weather-related delays. It can be applied as an adhesive or primer in ambient temperatures as low as 25 degrees Fahrenheit.

Fast, even aerosol application saves crews time while also increasing the coverage rate. Applied using a self-contained spray system, AeroWeb goes on up to 60 percent faster than traditional roller-applied adhesives. The web-like spray pattern also means that the adhesive must be applied to just 75 percent of the surface, versus 100 percent coverage with roller-applied adhesives.

A short tack time and long application window further boost crew productivity. AeroWeb flashes off in less than five minutes, so crews aren’t kept waiting. AeroWeb then remains sticky longer, enabling crews to work with larger sections of membrane.

According to the company, setup is minimal. Clean-up of tools and surfaces is fast and easy using UN-TACK safe solvent or mineral spirits. AeroWeb complies with VOC-related regulations in all 50 states. It is sold in #40 cylinders filled with 30 pounds of adhesive. One cylinder typically covers 1,000 square feet when used as a contact adhesive.

The Garlock Cyclone 5/15 Dual-Component Extruder is designed to significantly reduce the time and materials needed to adhere rigid insulation and cover boards to structural roof decks, as well as adhering fleece backed single-ply membranes in both new roofing and recover operations. According to the company, the Cyclone’s contained delivery system and free-flowing gun and hose design reduce the risk of catastrophic pump failure and costly downtime.

The Cyclone equally dispenses a two-component, 1:1 ratio low viscosity polyurethane adhesive, which allows projects to progress much more quickly than using multiple crews with hand caulking guns. Users can access connectors and load chemical containers from the front without kneeling or crouching, which minimizes downtime and operator fatigue. The Cyclone’s adjustable gun assembly and ergonomic design help reduce application errors and training time.

The product features a 1/2-HP electric motor, easy-loading barrel trays, and six solid rubber, flat-free tires. An optional generator mount allows an on-board generator to be tucked inside of the machine frame.

Leading Edge Safety introduces the ABO2: a patented self-cleaning, two-part adhesive applicator. According to the manufacturer, the product was designed with an integrated self-cleaning system to eliminate common problems contractors experience when applying two-part adhesives, including clogs, wasted material, and downtime spent replacing plastic tips.

When the AB02 is in the off position, the A and B resin lines are shut off and compressed air is introduced through a third connection. This forces adhesive all the way through the applicator and the plastic tip. According to the company, using the AB02 keeps roofers working more efficiently, reduces the need for tip changes, and minimizes wasted product.
